The energy range of sonic boom is concentrated in the 0.1–100 hertz frequency range that is considerably below that of subsonic aircraft, gunfire and most industrial noise. Duration of sonic boom is brief; less than a second, 100 milliseconds (0.1 second) for most fighter-sized aircraft and 500 milliseconds for the space shuttle or Concorde ...
According to the U.S. Air Force website, a sonic boom can sound like thunder and is typically caused by a jet moving faster than sound, “about 750 miles per hour at sea level.”
A boom occurs when an object travels faster than the speed of sound, releasing a burst of energy that sounds similar to an explosion and can shake and rattle objects in its path.
The sonic boom associated with the passage of a supersonic aircraft is a type of sound wave produced by constructive interference. Unlike solitons (another kind of nonlinear wave), the energy and speed of a shock wave alone dissipates relatively quickly with distance. When a shock wave passes through matter, energy is preserved but entropy ...
A sonic boom is a shock-wave, or pressure disturbance, caused by the movement of the plane through the air, much like the wave produced by the bow of a ship as it moves through water: just as the bow wave is produced for the entire journey of the ship, so the sonic shockwave occurs throughout the duration of a supersonic flight.

The boom was heard Sunday after the U.S. military dispatched six fighter jets to intercept an unresponsive business plane flying over restricted airspace. The Air Force gave the F-16s permission ...
This F-5E was modified by NASA for a constant area beyond drag optimum to reduce the sonic boom. The NASA Shaped Sonic Boom Demonstration, also known as the Shaped Sonic Boom Experiment, was a two-year program that used a Northrop F-5E with a modified fuselage to demonstrate that the aircraft's shock wave, and accompanying sonic boom, can be shaped, and thereby reduced.
The Forward boom state was 5.9 feet (1.8 m) long and had the smallest diameter of the three, while the Mid-Boom State was 4.3 feet (1.3 m) long and the second largest in diameter. [3] The spike, made of composite materials , creates three small shock waves that travel parallel to each other all the way to the ground, producing less noise than ...
